NAME
       inen - LANCE Ethernet network controller (88K only)

SYNOPSIS
       inen([controller-num[,,alt-ether-addr]])

DESCRIPTION
       The inen device driver allows an AViiON system that includes an
       integrated Local Area Network Controller for Ethernet (LANCE) to
       access an Ethernet network.  To configure such devices, you must add
       to the DG/UX system configuration file a device name entry of the
       form described in the synopsis above.  The parameters in a device
       name have the following meanings:

       ·   The controller-num parameter is a hexadecimal number which
           identifies the particular controller device.  Since only one inen
           instance is supported, the only supported value for this
           parameter is 0.

       ·   The second parameter position is unused, and is reserved for
           reasons of backward compatibility.

       ·   The alt-ether-addr parameter can be used to override the
           controller's default Ethernet address with a user-specified
           value, which must be represented as a string of exactly 12
           hexadecimal digits.  If no alt-ether-addr parameter is specified,
           the controller-resident default Ethernet address is used.

       The Internet address for each interface is specified at network
       configuration time with the SIOCSIFADDR ioctl; see ifconfig(1M) for
       details.

FILES
       Each inen device creates a single character-special device node when
       it is configured, with the pathname:

           /dev/net/inen(controller-num)


       The chk.devlink command is responsible for creating and maintaining
       an additional link to each inen device node, with a pathname of the
       form /dev/net/inen[0-9]*.  See the chk.devlink(1M) and devlinktab(4M)
       man pages for details.

       The inen device driver is a clonable Streams driver.  This means that
       you can open a single inen device node to access any unused minor
       device.  Each subsequent access of the node via the open(2) system
       call allocates a separate Stream (minor number) to the device driver.

DIAGNOSTICS
       Use the -i option with netstat(1C).

EXAMPLES
       The following entry in a DG/UX configuration file configures a LANCE
       controller to use its on-board default Ethernet address:

            inen(0)


       The following statement configures the same LANCE controller, but
       specifies an alternate Ethernet address:

            inen(0,,08001b123456)
